- Update config ID validation to query config_id_old field instead of user_id - Raise InvalidConfigError when config_id_old mapping is not found instead of returning raw ID - Add _resolve_config_id_old method to map legacy integer config IDs to UUID format - Enhance agent memory config extraction to resolve legacy int/string formats to UUID - Improve workflow memory node config ID resolution with proper legacy format handling - Fix memory config serialization to always use UUID string format - Update log messages to clarify config_id_old field references and resolution status
